The Electric Vehicle: Solving the Silent Problem

Abstract

Electric Vehicles (EV) are key stakeholders for a Green House Gas (GHG) emission free future. However, the integration of these vehicles in our society can create some collateral damage. The lack of noise of electric motors compared to Internal Combustion Engines (ICE) can lead to more accidents, as the acoustic signals from vehicles raise awareness of its presence. Pedestrians, Cyclists and very especially blind and partially sighted people are the groups at risk Thus, sound systems for EVs have to be designed and for that a study on the noise intensity in the frequency spectrum has to be made. This paper presents an experimental research on how to approach this problem.
